Successful Implementation and Value Validation of Dongyanbo Slotted Pipe Anchor System in Mine with Fractured Surrounding Rock

2026/04/30

I. Project Background

In recent years, with the accelerated development of overseas mineral resources and infrastructure construction, the demand for tunnel mining in the Rikita and Pole mines has continued to grow. Under deep mining and complex geological conditions, controlling the stability of the surrounding rock has become a core challenge for ensuring operational safety and improving mining efficiency. Local mining companies urgently need an efficient and reliable support solution to address issues such as fractured surrounding rock and high ground pressure, while simultaneously meeting the requirements for long-term safe production in the mine.

Against this backdrop, a well-known local mining company approached our company—Jining Dongyanbo Industrial & Mining Equipment Co., Ltd.—seeking a targeted mine tunnel support solution.

II. Needs Assessment and Solution Customization

Our technical team, in conjunction with the client's on-site engineers, conducted a comprehensive geological survey and operational condition assessment of the mine tunnel:

Geological Conditions: The surrounding rock is mainly composed of interlayered fractured sandstone and mudstone, with well-developed joints and fissures, making it prone to rockfalls and roof collapses;

Mining Needs: The tunnel has a large cross-section, a long service life, and needs to withstand long-term ground pressure and mining disturbances;

Core Requirements: The support materials must possess high tensile strength and rapid installation characteristics, while also incorporating mesh panels to achieve comprehensive surrounding rock confinement and reduce maintenance costs.

Based on the assessment results, our company customized a combined support solution for the client: Slotted pipe anchors + metal mesh:

Core Product: Dongyanbo high-strength slotted pipe anchors, made of high-quality alloy steel, achieve rapid anchoring through the expansion principle of the slotted pipe, eliminating the need for anchoring agents and improving installation efficiency by over 50%;

Supporting Product: Customized mining-grade metal mesh, working synergistically with the slotted pipe anchors to form a point-to-surface combined support system, effectively restraining surrounding rock deformation and preventing debris from falling;

Full-process Service: Providing on-site technical guidance, installation training, and after-sales maintenance to ensure the solution's successful implementation.

III. Implementation Results and Customer Value

The comprehensive application of this support system in the customer's mine tunnel project has achieved significant results:

Upgraded Safety: The combined support system effectively controlled surrounding rock deformation, preventing any roof falls or spalling accidents, and ensuring the safety of workers;

Significantly Improved Efficiency: The slotted pipe anchors eliminate the need for mixing anchoring agents, reducing single-bar installation time to less than 3 minutes. Combined with rapid mesh laying, overall support construction efficiency increased by 40%, accelerating tunnel excavation;

Continuously Optimized Costs: The product has a long service life, reducing the frequency of subsequent maintenance. Compared to traditional support solutions, overall operating costs are reduced by 25%;

Compliance and Environmental Protection: The product complies with international mining safety standards, leaves no chemical anchoring agent residue, and meets local environmental requirements.

Customer feedback: "Dongyanbo's slotted pipe anchor and mesh support system perfectly solved the surrounding rock stability problem in our mine's complex geological conditions. It is not only safe and reliable but also helps us improve mining efficiency, making it a trustworthy partner."

IV. Summary

Jining Dongyanbo Mining Equipment Co., Ltd., with its professional technical capabilities and customized solutions, provides efficient and safe support for overseas mine tunneling clients. The slotted pipe anchor + mesh combined support system, with its excellent mechanical properties and convenient installation, has become the preferred solution for mine tunnel support under complex geological conditions, helping global mining clients achieve safe, efficient, and sustainable production goals.
